The LLDP agent is configured to advertise the NE's public IP address as the local
management address. The operator cannot modify this configuration.
If LLDP is activated on the User Ethernet interface, it is enabled for transmission and
reception LLDPDUs (Transmit only and Receive only modes are not supported).
3.11.3.2 — SNMP MIB management
These default values are instantiated, with the appropriate scalar object, in the LLDPV2
MIB so that a Network Management System (NMS) could query them.
3.11.4 — Receiving nearest bridge LLDPDUs
The MPR-e terminates the Nearest Bridge LLDPDUs (untagged and tagged).
If the received PDU is identified as a Nearest bridge, then the MPR-e uses the PDU's
content to update its LLDP remote system MIB.
3.11.4.1 — Supported TLVs
Any other optional TLV different from Port Description TLV, System Name TLV, System
Description TLV, System Capabilities TLV and Management Address TLV of the received
PDU is not managed.
Management Address TLVs containing a Management Address Subtype other than IPv4
(IPV6 is not supported on MPR-e) is not managed and if such a subtype is detected the
corresponding entry in the lldpV2RemManAddr SNMP table will not be created.
A non-MPR neighbor may announce several management addresses in its LLDP PDU,
even a mix of IPV4 and IPV6 addresses. The MPR-e can store multiple IPV4 addresses; the
remaining IPV6 addresses are discarded.
